This invention relates to cleansing apparatus and more particularly tosuch 4apparatus in yconnection with certain portions of paper-makingmachinery which tend to be` and flexible means of control to meetvarying conditions of use. Another object is to provide apparatus of theabove nature inwhich the wear of the parts is reduced to a minimum.Another object is to provide a simple and highly eificient reversingmechanism. Other objects will be in partobvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,`combinations of elements, and arrangement of parts as will beexemplified in the structure to be hereinafter described and the scopeof the applicationl of which will be indicated` in the following claims.V

In order that certain dominant features of this invention may be themore readily .y grasped, it may be noted that in paper-makV ingmachinery there are pulp-supporting elements of the machine which tendto become clogged `with pulp andV introduce imperfec- APPARATS 192s.seri'ai- No. 290,763.

tions in the resilientfpaperl 'L Thisclogging kmay occur at variousportions of the surface Vand to varying' degrees; furthermore, there isacontinuous tendency to clogging even though it does not becomelocalized. l, Itis `also to be noted that in machinery of this sortthespace available for cleansing mechanism is cramped and the'conditionsofuse are severe. y To provide apparatuswhi'ch will efficiently meet thesesevere requirements and l' perform its functions in a practical anddependable manner is amongthe dominant aims of this invention althoughitmaybe noted that Acertain features herein setff'orth areyof advantageinother relations..

The hose 27 is provided Withsuitablev slack and leads upwardly over the roller 29 as indicated inFig. 2 ofthe drawings and under the roller 30 placed somewhat inadvance. of the roller 29. Engaging the hose onthe sides are a'pairofrollers 31 elsindicated in Fig. 1 j and it Will thus be seen that asthe hose travels into and out of casing 23 it rides upon these slightlyc oncaved rollers thus lessening the load on 'the` moving parts andgreatly reduc- 'ingthe Wear upon the hose.,

'- It'willthus be seen that in all positions oi y"the sleeve 19 alongthe threaded shaft 14 i the 'fitting 25 will readily Vassumea corre'- lsponding position andV carry With-it the fluid Vjet from the nozzle 34.v

There `isaccordingly' Yprovided reversing mechanism `whereby the nozzle maybeicaused to move baclrand forth across the part to be' cleanedfwithoutthel necessity for :reversal of thedriving mechanism. On thedrivenfsideof the clutch16 is a shorthollow Shaft section 36 which'terminates in a beveled pinion-37 having formed v thereonfa javv; clutchmember :38.

Thus, assuming that the direction ofdrive of shaft 14 is such as to move the sleeve-19 to the left, havingreference to Fig. 2 of the drawings, the shoulder 63 will engage andmove the stop 61, and by the means hereinbefore described actua-te thereversing mechanism to reverse the direction of drive of the shaft 14.Thereupon the sleeve 19 will travel toward the right, having referenceto Fig. 2, luntil the shoulder 64 engages and moves the stop 62 therebyagain actuating the reverse mechanism and again reversing the directionof drive of the shaft 14. -In this kmanner the ysleeve 19 automaticallyand positively travsubstantially no wear on the parts and no A apparatuswhich theseveral objects of this i mad-e of the above invention andasmany i GO uncertainty of operation. The threads on .the shaft 14 may beof any'desired size, and

the internal'threads meshing therewith h ave a continuous snug fit.Furthermore, the

mounting of the hose relieves his part of any l substantial .load andthere is no interference with full lubrication of the shaft and itsassociated parts as there is no leakage of water from the casing 23 tothe casing 11.'

In the use of apparatus of this nature often happens that there is anaggravated clogging of the web at some particular part, and it ispossible that with an ordinary regular back-and-forth movement of thejetthis clogged portion may be carried past vthe line of cleansing beforeit is engaged with suffi- -ci'ent severity by the cleansingr fluid.Thisk is provided for bythe hand control through the grip 60 of thecontrolling rod 59. By a slight longitudinal movement of this vrodv bvhand the reverse of the shaft 14 is effected at any time irrespective ofthe position of the sleeve 19 with respect tothe stops Gland 62. Thusthe nozzle and cleansing jet may be Caused to reverse their direction ofmovement at any desired instant and may be made to move back and forthquickly through a path of any desired lengthorpositi'onj to meet theparticular'conditions which are confronted. l y

It will thus be seen that there is provided .invention are accomplishedand which is well adapted to meet the conditions of hard practical use.Y
